摘要
采用线性最小二乘原理对从对流层顶10 km至地表0.8 km的温度探空廓线进行拟合,外插地表温度,讨论外插地表温度与实测温度的统计特性。将其应用于GPS气象中的加权平均温度模型发现,基于外插的地表温度能显著提高模型精度,提高约1.2~1.7 K。
In order to avoid the influence of human activities, this paper uses linear least squares to extrapolate surface temperature and to discuss the statistical characteristics of extrapolation surface temperature and the measured temperature. It then applies these results to the weighted average temperature model and finds that the surface temperature based on extrapolation can significantly improve the accuracy of the model by 1.2~1.7 K.
